Electronic keyboard instrument

Abstract

Electronic piano includes speakers arranged on its front side region and another speaker provided at a back position of the piano. Waveform memory provided in a tone generator section has prestored therein sets of four-channel waveform data, each of the sets corresponding to a tone. The four-channel waveform data are data recorded from a natural musical instrument via four microphones installed at sampling positions corresponding to the above-mentioned speakers. The microphones are installed with the on-microphone setting in which the microphones are positioned close to sounding members of the natural musical instrument. In response to depression of a key, any one of the sets of four-channel waveform data, corresponding to a tone pitch designated by the key depression, is read out from the waveform memory, so that the four-channel waveform data are supplied in parallel to the individual speakers.

Description

BACKGROUND[0001]The present invention relates to an electronic keyboard instrument which can achieve substantially the same acoustic effects as achieved by a natural musical instrument.[0002]Among the conventionally-known tone generation methods for electronic musical instruments are one which records waveforms of tones generated by a natural musical instrument, stores, into a waveform memory, the recorded waveforms of the tones as digital waveform data encoded by the PCM coding scheme or the like and then reads out the waveform data from the waveform memory when tones are to be generated by the electronic musical instrument.[0003]Further, among the conventionally-known piano-type electronic keyboard instruments (hereinafter referred to as “electronic pianos”) are one which has, as a tone source, a waveform memory that records (i.e., samples) tones of an acoustic (i.e., natural) grand piano in three channels in such a manner that a set of waveform data of three channels is stored in...

AI Technical Summary

Benefits of technology

The instrument achieves a highly realistic reproduction of the acoustic characteristics of a grand piano, providing a rich and immersive sound experience similar to that of a natural grand piano.

Problems solved by technology

However, the piano tone color (grand piano tone color) of the prior art electronic piano can not sufficiently reproduce the acoustic characteristics of the acoustic grand piano; particularly, the prior art technique can not achieve substantially the same acoustic effects as achieved by the acoustic grand piano, namely, it can not achieve a sufficient reality and depth feeling of a performed tone heard at the position of the human player.
